Bonds are often considered a more stable alternative to equities, but individual issues can differ significantly in terms of both returns and risk. The distinction between government and corporate bonds therefore lies not only in the interest they offer, but primarily in the creditworthiness of the issuer.

Who Borrows Money Through Bonds

By purchasing a bond, an investor effectively lends money to its issuer. Governments use bonds to finance public expenditure or existing liabilities, while companies raise capital for investments, operations or debt refinancing. The issuer undertakes to pay interest and repay the principal at maturity. The main difference therefore lies in who stands behind the bond and their ability to meet these obligations.

Why Corporate Bonds Usually Offer Higher Returns

Stable governments generally have broader options for raising revenue and refinancing debt, while companies depend more heavily on their sales, profitability and the business environment. Corporate bonds therefore usually offer higher returns as compensation for greater uncertainty. However, a high coupon does not necessarily indicate an attractive investment. It often points to a higher level of issuer risk.

Credit Risk: What Happens If the Issuer Fails to Repay the Debt

Credit risk refers to the possibility that the issuer will fail to pay interest or repay the principal. Its level depends on the financial stability of the borrower, which means that a large, established company may be more reliable than a smaller business or a heavily indebted government. Serious financial difficulties may result in delayed payments, debt restructuring or a complete default by the issuer. Government bonds should therefore not automatically be regarded as risk-free.

What a Credit Rating Tells Investors

A credit rating assesses the issuer’s ability to meet its obligations properly and on time. Investment-grade bonds are associated with relatively lower risk, while speculative-grade issues usually offer higher returns in exchange for a greater likelihood of financial difficulties. A rating is not a guarantee of repayment, however, and may change over time. Bonds without a credit rating therefore require a more thorough assessment of the issuer’s financial performance and the terms of the issue.

Interest Rates Affect Both Types of Bonds

Bond prices generally move in the opposite direction to market interest rates. When rates rise, older bonds offering lower interest become less attractive and their prices may fall. Bonds with longer maturities are particularly sensitive to such changes. Short-term price fluctuations may not be decisive for an investor who holds a bond until maturity, but selling it earlier may result in a loss (if you are interested in why interest rates and bond prices move in opposite directions, we explained this topic in greater detail in our previous article).

Liquidity and the Ability to Sell a Bond Before Maturity

Large government bond issues are often traded more actively, making them easier to sell. With smaller or privately placed corporate bonds, finding a buyer without accepting a significant price reduction may be difficult. The maturity date should therefore not be confused with the ability to exit the investment at any time. It only determines the date on which the issuer is expected to repay the principal.

The Role of Bonds in an Investment Portfolio

Government bonds issued by stable countries can reduce portfolio volatility, while corporate bonds may increase its return potential but also add credit and sector-specific risk. It is therefore advisable to spread investments across multiple issuers, countries, industries and maturity dates. Broader diversification can also be achieved through bond funds or ETFs (if you are interested in how different types of assets and funds can be combined into a simple diversified portfolio, you can learn more in our previous article).

The Choice Depends on More Than the Coupon Rate

When selecting a bond, it is not enough to consider only the interest rate on offer. Investors should also take into account the issuer’s financial position and credit rating, the bond’s maturity, liquidity and currency, the terms of the issue, and their own investment horizon. The chosen bond should also correspond to their risk tolerance and the role the investment is intended to play within the portfolio. Higher returns are rarely “free”; they usually represent compensation for assuming additional risk.
